@adsactly - "Do you think that existing financial system can be replaced with blockchain controlled systems independent from governments?"

Yes, they could. But presently the governments control the access to the crypto exchanges through their control of the internet. And governments aren't going to relinguish their control and power without a fight.

So the real question in my mind is "How can the crypto exchanges become independent from governments."

Note: This doesn't mean not paying taxes on earnings because I believe that people should pay their appropriate taxes which are set by each government.
